Research On Aware Data Transmission Algorithm For RFID-Oriented Opportunistic Network

with the continuous development of the Internet of Things,wireless sensor networks are becoming more and more widely used in life and work,however,in the air cargo field,there are still technical problems such as poor air logistics information,especially when using RFID tags to detect package loss rate,due to physical factors,the existence of opportunities network,field environment and attenuation and blind spots,data transmission often has errors and packet loss,so that the data of the network cannot be reliably guaranteed.Therefore,it is particularly important to study the reliability of data transmission in the opportunistic network of the RFID sensing layer.This paper first analyzes the RFID sensor network architecture from the background of the project,expounds the characteristics and technology application of RFID technology,and the research status of RFID at home and abroad.For the opportunistic network,the research overview of its congestion problem,the characteristics and architecture of the opportunity network,the research hotspots and the limitations of traditional opportunistic networks and algorithm classification are illustrated.Then analyzes and constructs the data transmission model in the aviation logistics warehouse,establishes the logistics sensor architecture of the air cargo,and analyze the positional relationship between the RFID tags and the reader sensor in the air logistics transmission environment and take advantage of the opportunistic network which proposes an intrinsic link between the density level of the read/write points and the packet loss rate of the data transmission,so that the data transmission loss rate is reduced.Finally,in order to solve the congestion problem of data transmission in wireless sensor networks,a scheduling algorithm for airport cargo station information collection is proposed.If a node of the system is congested,the node selection model of the multi-attribute decisionmaking,by selecting the appropriate node,constructs the distribution path and the original path to perform information transmission.If the path fails,the transmission rate is reduced.Relieve the purpose of congestion.The simulation results show that the algorithm proposed in this paper not only reduces the packet loss rate in the airport cargo station network,but also reduces the energy consumption of the system nodes and improves the reliability of the system data transmission.
